These 1 ing in 5 form. nd cutters and are adapted the so 1 slightly below the surface as the device is propelled.

.. bly mounted in the bearings 11 at of the straps 10, is a shaft 16.

in position thereon by means i?- This shaft projects some 'oi-d the sides of the frame and portions thereof are square r' n to rigidly receive in en -ncrewit'h, a plurality of clampiibers 18. The rear ends of these clamping members 18 whichproject slightly beyond the vertioal plane of the bearings 11, are enlarged to form heads 19 and the inner face of each head is provided with a clutch. "face. An additional head 20 also having a clutch face thereon, is brought into contact with each of the heads 19 and adjustably held thereto, by means of a bolt- 21 and nut 22. The heads 20 are formed on the forward ends of the arms 23 which may be of any desired length and it is obvious that through the medium of these clutch faces and adjusting bolts and nuts,

said arms may be disposed to various angles and positions with respect to the surface of the ground. The rear: end of each of said arms is also provided with a head 24:, the under face of which is provided with a clutch face and additional heads 25, each having a clutch fa.oe,'thereon, are brought intofirictional contact with the heads 24 and adjustably held thereto by means of bolts and nuts,- as used in connection with the first mentioned heads. These heads 25 are carried on projections from hubs 26 and rotatably carried on the inner end of each of said hubs 26 is a ground or cultivating disk 27. From the construction just described, it will be readily seen that these disks may be disposed to various angles and positions with respect to the ground and the main frame of the device, such adjustment being made possible by the ad ustability of the aforesaid heads with respect to one another.

ltigidly secured to and projecting forwardly from the shaft 16, is a lever 28, which provided thereon with a spring detrnt 2'51. A segmental rack or ratchet 30 is also provided, the lower end' of which is i e of the straps 10 and the up- I I, which i secured to a bracing the latter being, supported on the roar 'arr'eli It is obvious that from this construcciong the shaft- 16 may be partially rotated in the bearings by means-0f the lever to entirely raise the disks above the surface of the ground or lower the same into engagement with. the ground, as desired. When :irljtstcrh said lever may be retained in such position by means of this spring dctent.

An inverted U-shaped brace or support 32 is also provided, the arms of which are secured to the transverse bracing bar 7 of the rear arch and a seat 33 is mounted on the base of this inverted U-shaped support. This seat is disposed immediately adjacent the operating lever just referred to, whereby the driver of the machine will be in po-,

sition to operate the cultivating mechanism, at will.

Projecting rearwardly from the sides of the same as the device is propelled. It is I also obvious from the structure herein men tioned, and shown in the drawings, that as the shaft. 16 is partially rotated in the bearings 11, said. channelrshaped member will be raised or lowered, as the case may be.

From the foregoing description of the construction of improved device, the operation thereof will be readily understood and it-will seen that l have provided a device which is simple and durable in corn struction, inexpensive to manufacture and one which will he very efiicient and useful in operation.

While I have particularly described the elements best adapted to perform the functions set forth, it is obviou that various changes in form, proportion and in -the minor details of construction may bere-. sorted to without departing from the spirit or sacrificing any of the principles'of the invention.

Havin thus described this invention, what is laimed is 1. A cultivator of the class described comprising a frame consisting of a pair of runners, front and rear arches secured to said runners, side straps secured at their forward ends to the forward ends of the runners and inclined. upwardly toward their rear ends to be securcdto the rear arch, the free ends of said straps being designed to form bearings, a shaft mounted for partial rotation in said bearing cultivating mechaof angular plates, side straps secured to tion with said shaft, and means for the the forward ends of said runners and inmanual actuation of said shaft. 10 clined upwardly toward their rear ends to In testimony whereof I hereunto afiix my be secured to the rear arch member, the signature in, the presence of two witnesses. rear ends of said straps extending beyond l HENRY (J.
